Birthday Party Ideas for Kids in Purchase New York & West Chester

"Like Peter Pan's Neverland"

The kids had an amazing time zipping through the woods and courses. As parents, it was very gratifying to see the kids build their confidence through the courses and cheer each other to the next challenge level. At times, it felt like we were living out a scene from Peter Pan’s Neverland…simply magical. Thank you for making our daughter’s birthday an unforgettable experience. We especially want to thank the for being so polite, professional and helpful at all times.

Before You Book: Reserving

What are the requirements for booking a group?

There is a 10-person minimum for a discounted group rate. The reservation needs to be made 14 days in advance of the reservation. Lastly, there needs to be one person responsible for the reservation and payment.

If your group is less than 10 participants, please visit our general admission page or consider our frequent climber deals.

What is included in the birthday party package?

If you’ve been to Boundless Adventures previously, the experience is the same. Your participants are going to partake in a self-guided experience. We are always there to assist on an as needed basis.

  • The zip lining and obstacle course climbing activity (2.5 hours of climbing + 30 minutes for the orientation)
  • A picnic table (You are welcome to bring your own food and drinks)
  • One Boundless Adventures T-shirt for the guest of honor (When requested by you at check-in time)

What are the supervision requirements for groups with children 7-12 years old?

For groups including kids 7-9 years old, someone aged 16+ MUST accompany these participants on the course in a ratio of 5:1 for the first hour. After that hour, we require someone aged 16+ on the ground in a ratio of 10:1.

For groups including kids 10-12 years old, someone aged 16+ MUST be on the ground in a ratio of 10:1 at all times. If a chaperone chooses to climb, an additional chaperone needs to be on the ground to monitor the group.

If you need supervision, we can provide a guide for $50/hour or $150 for the entire party, subject to availability.

How do I reserve a group?

For small groups (10-20), you can call our office at 978-592-0017 or book directly on our website. If you choose to book directly, but have more than the 12 available for each time slot, book for 12 and email us at [email protected] as your RSVPs come in, so that we can add additional guests to your reservation. Keep in mind we are operating at restricted capacity, so the additions will be dependent on availability.

For groups of more than 20 guests, please complete the inquiry form above. Someone from our sales team will reach out to you shortly!

We require a 50% deposit to hold your date.

What times are available for group reservations?

Weekdays (Monday-Friday) – During general admission hours, we have set time slots open for group reservations. You can check the availability above.

During the spring and fall, when we are closed to the public on weekdays, we can open the park for groups of 20 or more participants.

Weekends (Saturdays, Sundays & Holidays) – Due to strong demand on the weekends, we have limited capacity for group reservations. The time slots are available on a first-come first-serve basis. They are often sold out more than a month in advance, so please plan ahead!

What is the group cancellation policy?

Cancellations made 30-60 days in advance of reservation

For groups consisting of under 25 participants, you will receive a refund of all amounts paid, less a cancellation fee of $150.

For groups consisting of 25 or more participants, you will receive a refund of all amounts paid, less a cancellation fee of $500.

Cancellations made between 7 to 29 days in advance of reservation

You will receive a refund equal to 50% of the contracted amount.

Cancellations made less than 7 days in advance of reservation

You will not be entitled to a refund. If something arises, or the weather is not cooperating, you can always reschedule your visit with no penalty, as long as you provide at least one hour advance notice.

Reductions in size of group within 7 days of event

You are responsible for payment in full for all participants in original group. As a courtesy, we will provide you with a maximum of 5 vouchers for a future visit to the park. To receive the vouchers, you must let us know at least 24 hours in advance of the reservation that your full group will not be attending the originally scheduled day/time.

No-Shows

If you fail to show on the day/time of your scheduled reservation you will not be eligible for a refund or credit.

What if I have last minute add-ons or cancellations?

We know it is challenging to provide an exact count! We wish we could let you tell us at the last minute. However, we have a limited capacity in the park, and the best way to accommodate the capacity constraints is to require payment in full for a firm headcount seven days in advance. If there are last minute cancellations, we can provide you with a credit for a future climb assuming there are at least ten participants present for the party and you’ve let us know at least an hour in advance of your reservation time. Last minute additions are welcome at the general admission rate (subject to harness availability). Keep in mind, last minute additions also lead to additional time spent checking waivers which can cut into your climb time.

Before You Come: Waivers

Where can I find the waiver?

When you reserve, you will receive a unique electronic waiver link in your email confirmation.

For Group Leaders: In your email confirmation, you will see a URL that says “Forward this link to all of your guests”. This link is tied to your specific event. That will link your guests’ waivers to your party. Even if your party guest has been here before, we ask that they still click on the link and provide their email address to link their waiver to your party.

You will also receive a link entitled “Group Waiver Management”. This will provide you with a real-time picture as to who has completed the waivers. We ask that you put checkmarks next to the participants, and mark those that are not attending, as “not participating”.

Group Guests: Please contact your group leader, and ask them to share the waiver link with you.

Why is it important for all of my guests to complete the waiver in advance?

We want your event to exceed your expectations. The first step is to ensure a smooth check in process. If the waivers are not completed in advance, it can delay your start time by up to an hour. Often, the end time is set on your invitations. Hence, a delayed start can result in an abbreviated climbing experience.

In your email confirmation, you will see a URL that says “Forward this link to all of your guests”. This link is tied to your specific event. That will link your guests’ waivers to your party. Even if your party guest has been here before, we ask that they still click on the link and provide their email address to link their waiver to your party.

You will also receive a link entitled “Group Waiver Management”. This will provide you with a real-time picture as to who has completed the waivers. We ask that you put checkmarks next to the participants, and mark those that are not attending, as “not participating”.

We know this seems complicated. That is because often mom completes the waiver, but mom isn’t participating. Other times, someone completes the waiver, but has a conflict and is unable to attend. You are the one who needs to tell us who is part of your party, and who is not.

If you arrive with all of the waivers completed in advance, and your guests arrive on time, we guarantee that you will not be delayed!

If my guests have been to Boundless Adventures before, do they need to complete the waiver again?

Waivers are valid for each calendar year. However, we need to know who your guests are. In your email confirmation, you will receive a link to your individual event management waiver portal. The first step is to provide your guests with a link to this portal either by emailing directly from the portal or copying the link into an individualized invitation. When they click on the link, it will ask them if they already have a waiver. The system will ask your guest for the email address associated with their waiver. They simply need to provide the email address and hit submit to link them to your event.

Planning Your Event

What time should I tell the parents to pick up?

The party time is 2.5 hours. If you want to provide food, that would require additional time, typically 30 minutes.  Also, for larger groups (20+), the check-in time can be a bit longer due to unforeseen group dynamics. Please be patient as safety is more important than speed.

What happens if a guest is going to be leaving early or arriving late?

If a guest needs to leave early, we ask that you let us know prior to starting. We can mark on that guest’s ticket an end time that meets your needs, so that the guest won’t be midway through a course when it is time for them to leave. If you are unable to tell us in advance, we will do our best to get your guest off the course in a timely manner. However, please understand that safety comes first.

If someone needs to arrive late, do not worry! We can get the latecomers harnessed and briefed quickly. Each course takes approximately 30-45 minutes to complete. They can join the group upon completion of one of our courses.

Do you offer goodie bags?

We do have an optional goodie bag available for your convenience. The cost is $12/bag. The bag includes a canvas drawstring bag, climbing gloves, a coupon for your guests’ return visit, and several other surprise goodies!

Do you have custom Boundless Birthday invitations?

We sure do. Click here to download:

Can I get food delivered to the park?

You are welcome to order food from the local vendor of your choice.
Berlin Village Cafe is a local pizzeria that we are working with to provide reliable delivery to the park. You can reach them at 978-415-0291. Another great option is Vina’s Pizza

What if it rains?

Our aerial adventure park is open rain or shine. If you decide that you want to change the date, we will do our best to accommodate you. If the park is unable to open or is forced to close prior to your visit, you are given the option to reschedule your outing or to receive a full refund.

Please refer to our Weather Policy for more information.

During Your Party

Do you offer group facilitators or guides to help with the group event?

This is a self-guided activity. We do offer guides at a cost of $50/hour. Typically, guests utilize this service for their last hour of climbing, when they are looking to be their most adventurous selves! If you are interested in doing this, please call our office two weeks in advance of your visit to ensure the availability of a guide. If it is within the two weeks, we will do our best to accommodate your request.

Would you like a guide for the entire party? When you have a guide for the entire party, they can assist with the check-in process, facilitate food deliveries, set-up your table area, take care of late arrivals/early departures, and climb with the guests. The cost is $150. But remember, they are one person! If you want them climbing with the kids the entire time, then you will need to manage the other responsibilities. 

Is there a place and time for us to eat?

All group reservations are provided with picnic tables based on your group size. The tables are yours for the duration of the event, as well as 30 minutes after the event ends.

Are there any general rules that I should make my group aware of?

Please read our rules and general FAQ.
